UNITED TATE Psi-Eur enrich CHARLES EQAfiKE I rIf AND IlTHAMARF. RANDOLBH, or IOLA, ansas.

all whom itmay concern: i

United States, residing at Iola, in the county of Allen, State of Kansas, have invented a new-and useful Oil-Burner, of which the/following is a specification. i

r 'This invention relates to hydrocarbon burners for use in connectlon with cook ng stoves, heaters, furnaces, etc.' x i The ob3ect of the lnvention is to provide simple and eflicient-nieans whereby oil and steam under pressure can be thoroughly C0111- nnngled and'dlsch'arged 1n the form of a et 1 51-5 into the fire box or other compartment where it is to be consumed. 3

'A further object is to provide a burnerof,

thischaracter inwhich steam is used as one of the parts of the fuel, said steam being gen- 120 erated by the products of combustion produced at the'burner. r, v

Another object is to provide a burner designed to be laced outside ofthe fire box and so positions as to-injectajet of"-co1nbusti ble gas into the fire box where co mbustion occurs, the burner bemgfthusmaintained' practieallycoolat all times. 1

Afurth'er objectis to provide simple and efiicient means for controlling the discharge 340 ofcombustible fluid froin'the burner'head,

said means also serving to direct a jet of combustible gas in various directions within the fire box. a

With these and other objects in view the invention consists of-certain novel features of' construction and combinations of parts which be "hereinafter more fully described and pointed out in the claims.

In the accompanying drawings is. shown the preferred form of the invention. w

a I a a. I formed within this dome is a steam passage 7 Be it known that we, CHARLES FRANKLIAE and ITHAMAR ERANB L'PH, citizens ofthe extending horizontally and communicating at its inlet end with a pipe Qwhich is'screwed I or otherwise fastened within the plate 3 as indicated at 8; This pipe 9 is extended any desired distance within'the casing 4 and terminatesin a tubular arch 10 designed to receive water from a longitudinally extending pipe 19 connected with a supply. pipe 23, there being a suitable valve 24 for controlling the passage of water from the supply pipe to the pipe 19. center of the dome 1 and directly above a vertical oil assage 11 which is cast or'otherwise forme, within the dome 1 and receives oil through a pipe 13 from a supply pipe 20, there being a suitable valve 21 for controlling "the passageof oil from the supply. pipe 20 to the pipe 13,; I I v The; passages 7 and 11 form a mixing J chan1her14 atatheir, meeting ends, said mixing chamber being disposed directly upon the central portion of the dome 1 and having a flaredgutlet port 17 opening therefrom and into the center of the recess 2. 'A screw plug 15 is mounted within the outer wall of the mixing chamber 14 an d with its longitudinal axis extending through the cgnter of the port 17 and projecting from the inner end of this screwplug is a regulating needle 16 extending directly through the center of the port 17 and having its free end arranged within recess 2 a and preferably slightly curved as formed in the upper portion of the endef the 'dome and is normally closed by means of a plate 27 mounted on a suitable pivot 28, this plate being disposed to he swung so as to partly or entirely expose the opening 26 and thus regulate the supply of air to the interior of the dome. a 1 Supported below the the arch 10;is atray 5 designed to be attaehed to the plate '3. in any preferred manner and thusheld-dn'fixed relation to the pipes. A grate 15 is arranged adjacent one end of this tray.

In using the device herein described fuel is placed in the tray 5 and'ignited so as 'to heat the pipes 9 and 19 and the arch 10. After these'pipes have been suflieiently heated water is admitted to the pipe 19'by opening valve 24 and i i-passing through said pipe and-the arch {10 and pipe 9it will be converted into steam. The valve 21 is also openedand oil is free to pass into the passage Passage 7 terminates at thev pipes S and 19 and 'chamber 14 in a will occur within the casin 7 and will flow upwardly into the mixing line at right angles to the direction in which the steam enters said comartment through the assage 7. The two uids, steam and oil,vwill thus come together along intersecting paths within the mixing chamber and the oil be finely divided by the steam and the two fluids thoroughly mixed. They will then escape in the .form of a jet through the ort 17 and this jet can be controlled by at justing the plug 15 from or toward the-port. The gas'or va or in escaping through the port will tend to ling the needle 16 and inasmuch as the terminal of this needle is slightly bent as indicated at 18 the et can be discharged anywhere on 1: fixed circle within the recess 2 and casin 4 simply by turning the plug 15 so as too ange the direction in which the needle points. The jet will of course be expelled into and beyond the recess 2 and the ignition thereof at a point removed fromthe port 17. y opening the closure or plate 27 a desired quantity of air can be admitted to the recess 2 so as to afford complete combustion and eliminate the roaring sound usually produced by the combustion of fuel of this nature. As combustion occurs at a point removed from the port 17 the domel is maintained practically cool at all times and there is no danger of any hydrocarbon deposits baking or congealing within the burner as a result of the heat and thus interfering with the proper flow of the combustible fluid through and from the burner head. It will be seen of course that. after steam has once been generated and the combustible mixture discharged from port 17 and ignited the heat produced by combustion will be sufficient, to continue the genera- 't-ion of steam within the pipes 19 and 9 and the arch 10 without the use. of further fuel within the tray 5. vThe grate 15 is used to permit the escape of ashes, etc-1., produced during the starting of the burner.

What is claimed is:

1. A burner comprising a dome havin a central mixing chamber therein, there being oil and steam conducting 'assages entering said chamber at right ang' a water conducting pipe opening into the steam passage and extending beyond one face of thedome, said pipe constituting a vaporizer, there being an outlet port extending from the mixing chamber and through the dome for directing a combustible mixture es to each other,

from said chamber and in the direction of the vaporizin pi e, threaded means for controllingthe disc arge of fuel through the port, and means carried thereby for controling the direction of movement of the fuel upon leaving the port.

2. A burner comprising a dome, said dome having a mixing chamber, there being an outlet port extending from the mixing chamber and through the dome, means for controlling the discharge of fuel through the port, and means carried by the controlling means for controlling the direction of movement of the jet of fuel upon leaving the port.

3, A burner comprising a dome having a mixing chamber therein, said chamber having inlets and an outlet, the outlet 0 ening into the dome, means for controlling t 1e discharge of fuel through the outlet, and a curved needle carried thereby for controlling the direction of movement of the fuel upon leaving the outlet.

I 4. A burner comprising a dome having a mixing chamber, there being oiland steam conducting passages entering saidchamber, a Water conductin pipe opening into the steam passage an extending beyond one face of the dome, said pipe constituting a vaporizer, there being an outlet port extending from the mixing chamber and through the dome for directing a combustible mixture from saidchamber and in the direction of the vaporizing pipe, means for controllin the discharge of fuel through the port, an

means carried thereby for controlling the direction of movement of the fuel upon leaving the port.

5. 'A burner comprising a structure having a nnxlng chamber therein, there being inlet ports and an outlet port opening into and from said chamber respective a screw plug for controlling the passage of fuel through the outlet port, and a curved needle outstanding from the plug'and extending through the outlet port, said needle being revolublc with the plug for controlling the direction of the fuel 11 on leaving said port.

In estimony that we claim the foregoing as our own, we have hereto affixed our signatures in the presence of two witnesses.
